Better than that: please provide LilyPond code. It's very hard to 
diagnose problems otherwise. Cf. https://lilypond.org/tiny-examples.html


The only case I know of where LilyPond will remove the hairpin on the 
next system is if it ends on the first note of that system, e.g.

\version "2.22.2"

{
  c'1\< \break c'1\!
}


in which case you can apply the technique from 
https://lsr.di.unimi.it/LSR/Item?id=804 as Andrew said to show it 
nevertheless:

\version "2.22.2"

{
  \override Hairpin.after-line-breaking = ##t
  \override Hairpin.to-barline = ##f
  c'1\< \break c'1\!
}
